The PEMFC electrolyte is a relatively poor ionic conductor (10S/m at 80C). However, if the electrolyte is too thin, fuel crossover will become too severe. Electrolyte resistance ileak gives rise to a loss of the form leak=A ln ileak ( symbolizes voltage loss). Furthermore, given current density i, determine the optimum electrolyte thickness that minimizes ohmic+
